This business of 'you don't look your age' ... What does it mean exactly? And mind you, I'm guilty of saying it too! I intend it as a compliment of course, and I know that when people tell me I don't look 50-something they are saying I look younger. But, is that a good thing?

In a culture where someone live-tweets a birth and in the same week a 70-year-old announces to the world that she's tired of being a virgin and is looking for someone to do something about it, maybe it's time to have a national conversation about what it means to "act appropriately."
